<p>The present invention relates to a multifunctional combination probe, which is mounted on a holder of a temperature determination lance during a refining step in a steel mill and is then immersed in molten metal, thereby performing sensing functions such as temperature determination and oxygen determination or the like for the molten metal and sample extracting functions. The present invention, a combination probe for a dual sampler, comprises: a shell block that has sampling cases for sample extraction and a sensor, and is mounted at the end of one side of a long axial multi-protection pipe; and a connector that is electrically connected with said sensor, wherein said shell block has sensor holes which are disposed to allow the two sampling cases and the sensor to be inserted thereinto. According to the present invention, the combination probe obtains information on temperature determination and oxygen determination for the molten metal by a one-time measurement with the probe and extracts two samples at a time, thereby protecting against analytical problems which may occur, and contributing to an increase in refining efficiency and cost reduction, and can further be applied to various grades of steel.</p> |
